Gly-Pro-Ala peptide and FGSHF3 exert protective effects in DON-induced toxicity and intestinal damage via decreasing oxidative stress

FGSHF3 and GPA peptide activate Nrf2 to up-regulate the expression of antioxidant enzymes, resulting in suppressing oxidative stress in intestinal. Ultimately, FGSHF3 and GPA maintain the intestinal barrier and inhibit DON-induced toxicity.
